Decided last minute to drop in to Orlando Speedworld last night. 2 child seats in, 3/4 tank of e50 and no adjustments to tire pressure. I did the BMS Flash to my JB4, otherwise my 13 335iS is stock w/2k miles. DCT.
I did two other runs at 12.1/12.2 but my traps were 116. Even though my 60 ft's are 1.9 on RFT, I'm breaking loose mid 2 gear thru third and DTC is kicking in hard hurting my 330.

Buraq, I'm shifting around 6k rpm and def into 5th at the end. Although I could hold 4th and may try that. Boost is around 17-18, tapering off to 14-15 at 6k rpm. My timing is around 10 advance, and trims are really low so I might bump up 1 to 2 psi.

Are you shifting to 5th?

I am long in 5th before the end. I believe your boost is dropping off earlier than your expecting in 4th gear.

you might want to shift out of 4th just before 6k rpms. 5th gear is where the beast comes out and will see relitively more boost compared to 4th.

run couple of logs from 3rd - 5th gear shifting at 6500 rpms and you will see what I am talking about

Also helps that the 335is has a DCT and more aggressive timing curve. Throw some sticky tires on there and 11s for sure!

Ok but the BMS flash is useless for stock turbos. I guess the DCT and launch control makes a big impact.

I saw your other comment noting he was on e50 so I'm not sure if this comment is still applicable, but do you still believe that the flash doesn't benefit the fueling for the stock turbos? If so why do you believe so? I'm just curious

I was told that the flash isn't beneficial for stock turbo applications if using Meth and 94 oct.

Depending on the amount and concentration of meth used, you might pick up a little bit of power going to a more aggressive timing curve, but it's certainly not worth the price of a Cobb.
